Experimental research of the NN scattering with polarized particles at the VdG accelerator of Charles University. Project 'NN interactions'

The purpose of the project is to study three-nucleon interactions using 14-16 MeV polarized neutron beam in conjunction with polarized deuteron target. Spin-dependent total cross-section differences DELTA rho sub L and DELTA rho sub T will be measured in the energy range, where there are no experimental data, with sufficient accuracy to check the contribution of the three-nucleon forces. In the test run, the obtained deuteron vector polarizations were P sub - = (- 39.5 +- 2)% and P sub + = (32.9 +- 2)%. The proposed experiment is the continuation of the preceding measurements of the same quantities in the np scattering at the Van de Graaff accelerator of Charles University
